Was wondering if I can run the stock carbs jetted on this set up, don't know anything about engine except has Paul Turner National engraved on cylinders and midrange engraved under reeds, just picked banshee up so don't know anything about it, also has #5702 engraved in the jugs. Any info or where to get info would be appreciated thanks, bike idles and runs but lacking acceleration has 25 pilot 300 mains.
